Traffic Assistant is app for monitoring traffic on your favorite traces.
You can find out delay and traffic congestions on your way only by one click. Or you can set up automatic notification and app warns you at specified time in a case of any problem on your way.
Your trace can be defined by an address (start, destination and max three waypoints). Other possibility is to define destination address and the start position will be obtained by GPS.
UPDATE: You can track your refuelings, fuel consumption, fuel costs and other vehicles costs.
The trial version has the full functionality and all features, but contains ad.
